The U.S. Army Corps of Engineers, Portland District has a new requirement for a New 130 Ton, Submerged Traveling Screen (STS) Gantry Crane, at the John Day Lock and Dam, near Rufus, OR.

A formal solicitation will follow this announcement (currently planned for mid-May). This work consists of replacing the existing John Day Dam Powerhouse Submerged Traveling Screen (STS) 90 Ton Gantry Crane located at the John Day Lock and Dam, near Rufus, Oregon.

This project will consist of designing, manufacturing, factory testing, transporting, erecting, and field testing a new 130 ton, outdoor gantry crane comprising of a main hoist, an auxiliary hoist, and a latching hoist. The crane system will have built-in capabilities to meet a range of operating conditions, and modes that include: variable speed control; interlocking operating mode controls to eliminate operating hazards, reduce safety risks, and prevent use of systems that could result in equipment damage. The crane will need to be able to adapt to lifting different loads and load types under changing outdoor environmental conditions (such as high winds and variable weather conditions), and the ability to manage and handle loads underwater over a wide elevation range. In addition to the new crane work, the contractor will deconstruct/disassemble the existing 90 Ton STS Crane and safely remove it, in compliance with all environmental requirements.
